Why the banks have the power to commit crimes with impunity ?

Legally, the TBTF banks are indistinguishable from the King, since the power to commit crimes with impunity swallows all other sovereign powers; such a power isn’t even supposed to exist in the U.S., and yet it does. Moreover, since there can’t be two kings in a kingdom, the entire U.S. government, from the president on down, is just one of the King’s men under this formulation of power. The real job of the U.S. government, then, isn’t to represent the will of the people at all, it’s to do the King’s bidding. A nation that isn’t governed by law is governed by instead by a king—it’s one or the other—and the president’s inferiority to such an above-the-law sovereign was confirmed over 40 years ago with Nixon’s ouster. The president, unlike the King, answers to the law (despite Nixon's opinion).
